Slant six distributor drive gear

My picture was to aid in aligning the top advance plate to the lower shaft with the gear on it. If you get them 180 out it will be hard to drop the dizzy back in the same position it was pulled from. This will cause the timing to be off and the car hard to start. The distributor adjustment is on the small side. I made the picture for my own use and felt it would be helpful and a nice reference. This info is not in any shop manuals that I have.

It is important for people to understand that the diagram with respect to the drilled hole(s) is unique to your distributor. The replacement gears that I obtained had only one hole drilled and the one hole could be 180 degrees off and not relatively indexed the same in any event. Your diagram would be very important for people to make when they disassemble their existing distributor for some reason and retain the same gear.
